Disassemble the iPhone XR. Use qianli 3D screwdriver and CPB screen separator to open the iPhone XR screen. Remove the iPhone XR display assembly, disconnect the battery, and then take off the iPhone XR motherboard.

We noticed that this iPhone XR has repair marks.  The baseband shield cover has been disassembled, and there is repair sticker on it. And we found that the iPhone Nand flash also been repaired before, because there are some black glue around it.

Remove the repair sticker, obviously the iPhone baseband has been repaired before, the capacitors and resistors around it has been corroded and blackened.

Use Jabe UD-1200 soldering iron to smoke rosin to the motherboard, so the solder oil for the bottom pin of the IC assembly can be replaced.

Use hot air gun and tweezers to remove the iPhone baseband. Put the iPhone motherboard under a microscope to observe, the iPhone baseband IC doesn't looks good. Apply some solder paste to the baseband, and then reballing it.

After reballing, assemble the iPhone XR to test it, but the failure is still the same.

Use ADMS9 digital multimeter to measure the resistance value for the iPhone baseband power supply, we found all resistance value measured are normal.

Check iPhone motherboard again, we found the RF IC also has been repaired before, use hot air gun and tweezers to replace the RF IC, and then assemble the iPhone XR.

Now restore the iPhone XR with iTunes, and then follow the tips to activate the iPhone XR, it goes well, the iPhone XR was activated successfully.

Troubleshooting: iPhone 7P get boot failure after dropping

This iPhone 7P get boot failure after dropping, press the iPhone power button, the iPhone has no response, in a word, the iPhone 7 plus won't turn on.  We need to fix it.

Use phone disassembling tools to disassemble the iPhoen 7P, remove the iPhone display screen, disconnect the battery, and then take out the iPhone 7P motherboard.

Use UNI-T UTP3305 DC power supply to measure the iPhone 7P motherboard , trigger it, the current up to 60mA and then downs to 0, the current jumps like this over and over again, which is abnormal.

Use digital multimeter to measure the relevant voltage for the RAM, they all normal.

As we know, for the drop-damaged iPhone, the iPhone CPU virtual welding is more likely. Put the iPhone motherboard on the PCB holder fixture, and then put it under a Trinocular Microscope.

Use BGA graver blade to remove the black glue around the iPhone CPU to check if the iPhone CPU is virtual welding, but it's normal.

Based on our experience, the RAM for drop-damaged iPhone 7P is easy to short, let's remove the iPhone CPU, after removing CPU, we found the solder pad missing some pins.

Use JBC CD-2SHE soldering iron to clean the solder pad, and then solder the missing pins. After handling the solder pad well, install the iPhone CPU back to the motherboard.

Now measure the iPhone 7P motherboard with UNI-T UTP3305 DC power supply, the current tested is normal.

Install the iPhone 7 Plus, press the power button, the iPhone 7 plus is turned on successfully.

Best replacement way for iPhone 11 Pro Max A13 RAM

Here is a replacement way for replacing iPhone iPhone 11 Pro Max A13 upper layer. Use screwdriver to remove the screws at the bottom of the iPhone screen, open the screen with a LCD sucker. Remove the iPhone display screen, disconnect the battery, and then take out the iPhone 11 Pro Max motherboard.

Put iPhone 11 Pro Max motherboard to the SS-T12A heating station for separating the board, take off the iPhone 11 Pro Max motherboard upper layers, and attach it to the MJ K30 PCB holder.

Put iPhone motherboard under a Stereo Zoom Microscope to observe the A13 SDRAM, it looks good. Now use QUICK 861DW hot air gun and CPU removal blade to remove the A13 SDRAM, insert the blade from the right corner of the A13 CPU, and then slide to the top right corner. Once the SDRAM has been removed, next we need to remove the glue.

Use BGA removal blade to remove the glue on the CPU, and then clean it with PCB cleaner. Now connect the iPhone 11 Pro Max motherboard to the DC power supply to measure the current, after measurement, the current is normal.

Place the A13 upper layer to the right position, and then use hot air gun to install it back the motherboard.

Once down, cooling the motherboard, and then install the iPhone 11 Pro Max.

Press the iPhone power button, the iPhone 11 Pro Max turns on properly, and then test the iPhone functions, everything works well.

Drop-damaged iPhone XS Max Face ID not working- Fixed

 Here is a drop-damaged iPhone XS Max, the result is that the iPhone XS Max Face ID is not working. How to fix it?

First, we need to disassemble the iPhone XS Max. Use phone screen opening tools to disassemble the iPhone XS Max, remove the iPhone XS Max display screen and iPhone battery, and then take out the iPhone XS Max motherboard.

Use SS-T12A heating station to separate the iPhone XS Max motherboard, and then put it on the iSocket test fixture.

Use digital multimeter to measure the resistance value for iPhone XS Max Face ID connector, when we measured the 17 Pin of the infrared camera, we found it had no resistance value, but the value for the 15 Pin was normal, which is why the iPhone XS Face ID doesn't works. The circuit between the iPhone CPU and iPhone infrared camera 17 Pin are virtual-welded or disconnected.

Now we need to remove the glue for iPhone CPU, put iPhone motherboard under a microscope, and then use BGA graver blade to remove the glue around the CPU.

Apply some solder paste around the CPU, and then use QUICK 861DW hot air gun and BGA graver blade to remove the iPhone CPU. After the iPhone CPU is removed, use soldering iron to handle the residual glue on the solder pad, and then use JBC CD-2SHE soldering iron to solder a jump wire from 17 Pin to test if the circuit between iPhone CPU and iPhone infrared camera 17 Pin are disconnected.

After soldering, measure it with digital multimeter, the data tested is normal, now we confirm that the iPhone CPU is virtually welded, we need to re-install the iPhone CPU.

Reballing the iPhone CPU, and then install the iPhone CPU back to the motherboard. After the motherboard is cooled, use digital multimeter to measure the 17 Pin, now the resistance value is back to normal.

Next, use iSocket test fixture to test it, the iPhone XS Max Face ID tested is normal. At last, install the iPhone XS Max.
